Emby unstable since lasts updates.

May 27, 2016

Since im updated from 3.0.5818-1 to 3.0.5971-1, emby has become completely unstable.

It oftens restarts by itself while using web gui, or just stops responding, throwing 500 errors when querying /, requiring a manual restart.

Playing video also fails.

pacman logs :

[2016-05-26 09:38] [ALPM] upgraded emby-server (3.0.5818-1 -> 3.0.5971-1)

[2016-05-27 18:22] [ALPM] upgraded emby-server (3.0.5971-1 -> 3.0.5972-1)

Since these two updates, emby is unusable.

GUI will often send me thoses :

No logs will be added to system logs, except if the app completely crashes, leading to systemd restarting it automatically.

Playing videos will start but crash after just a few secs, getting this kind of logs in browser's console :

Most of the time, a failure at playing video will lead emby to also thow 500 errors afterwards, when querying home.html.

Latest logs from emby :

https://www.friloux.me/tmp/emby/server-63599972526.txt

Logs indicate a too many open files error.

Seems an automatic scan is started when emby is starting, and i believe it is it that leads the server to hell.

I also lost a damn lot of movie covers when upgrading, leading me to spend a few hours setting them manually between crashes.

I am on my way to increase the max open files limit on my system, but everyone should agree that something is not going well.

Output from lsof : https://www.friloux.me/tmp/emby/lsof.txt

Am i guessing right if those pipes are pipes openned to read/write to ffmpeg/ffprobe process ?

Seems like a change since 3.0.5818-1 leaves pipes opened (or the problem had always been there but hided by the fact that automatic scans did not update everything ?).

Looking for more ideas from you guys.

Hi, can you please attach the log files? those links create this.

Thanks.

Ah, also forgot a thing : Starting emby thows lots of errors : http://0bin.net/paste/sFdl+X25UAC6LaOK#2J0cAFF0giObzMC-n4EEl43o0IrTPav95l+RwFEAN/y

This is because the cert is signed by CA-Cert and that your browser doesnt trust them.

Will tell you if problems still happens.

Try the latest stable version of mono - 4.2.3.4. You are running 4.4 which is still pre-release, and we've seen a number of issues with it.

May 27, 2016

Edit: Ok, saw above, thanks.

May 27, 2016

It seems you guessed right!

No crash since i downgraded mono.

I did let a playlist to run while having diner, it was still working when back.

On the dashboard i can see :

Convert media

55.0%
Scan media library

45.4%

And no crash, it used to crash at ~10% everytime since yesterday.

So a great thx for fast replies and perfect troubleshooting!

May 27, 2016

Well done, thanks for reporting back.

May 27, 2016

Just so you know, i started a thread on the archlinux BBS ( https://bbs.archlinux.org/viewtopic.php?pid=1630299#p1630299 ) so you're not alone having feedbacks about this breakage.

May 27, 2016

Thanks, yea. i don't know why they decided to mark 4.4 as stable. It's been that way for over a month even back when it was in early alpha stages.
